2 Referenced Standards
The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards are subject to revision, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB 17421.1-1998 General Rules for Machine Tool Inspection Part 1: Geometric Accuracy of Machine Tools under No-load or Finishing Conditions 3 General Requirements
3.1 When using this standard, reference should be made to the relevant provisions of GB/T17421.1, especially the installation before inspection, the idling temperature rise of the spindle and other components, the inspection method and the accuracy of the inspection tools. 3.2 Refer to the provisions of 3.1 in GB/T17421.1-1998 to adjust the installation level. The leveling must be in accordance with the method specified by the manufacturer. 3.3 Before inspection, the actual inspection sequence can generally be arranged according to the requirements of the installation and disassembly tools, inspection convenience, and thermal inspection items. 3.4 When the measured length is different from the length specified in this standard, the tolerance should be converted according to the measurable length according to the provisions of 2.3.1.1 in GB/T17421.1-1998. When the conversion result is less than 0.001mm, it is still calculated as 0.001mm. 3.5 When inspecting the working accuracy, the test piece should be inspected after fine grinding. 3.6 According to the agreement between the user and the manufacturer, the inspection items can be increased or decreased. 3.7 For the sake of simplicity, the schematic diagrams in the two chapters of pre-adjustment inspection and geometric accuracy inspection in this standard only include one form of machine tool schematic diagram.
